` To all ichom it may concern.:

lie it kiiowii that l. (iixiaoi: Bi'iiaox, ii citizen of tlie United States, i'esiding at 'iiiiiinuc. iii tlie county o of liidianu, have invelited iicw and useful liiipi'ovcinents in l'ixplos'ive-l'higine `*tartei's. of wliicli the following isu specification.

This' inveiition relates' to cxplosive engine startei's and is eslxw'iully designed witli reference to the needs of iiiotoi'mcii iii starting the engine of motor vehicles. uvoiding tlie nem'ssity of erankiiirthe engine as iiow coiiiinonly resorted to.

With tlie above aiid other objects iii view, tlie nature of wliicli will inore reudily appear as the descript'ioiii'eeds, the iiivention consists iii the novc construction, combination and arran 'meiit of parts as lierein fully desci'ibed, illustrated uiid clainied.

Fig. 2 ia u vei'tical cross section oii tlie liiie 2-2 of Fig. 1. Fig. 3 is a side elevatioii of the iiaiin part of the starter. Fig. 4 iii a Vertical cross section through the same oii the line 4-4 of Fig. 3. Fig. 5 is a Vertical loiitzitudinal section on the line 5-5 of Fig. 4. Fi (i is nn enlargul detuil i'spcctive view o ,one of the riii 'a or bhi es and the parts ai-iso'ciatcsl therewitli. Fi 7 ia a liorizontal section oii the line 7-7 of `ig. 5.

'l`he motor vehicle to which the inveiitiofi is applied with a eoiiipreieied fluid tank t from 'vhich a. feed pipe 2 leads'the eoniprsd'fluid'iiito a cy inder iiidicated ii t 3 or iiu nirting inovement to a pistoii working iii sali .-cyliiider. Any suitable means iiiiiy be eniployed for eoiiipressin the tiuid iii the 'tank 1 as by the engine itscl or by means of a'n aiixiliary air couipreaeor iiliown a 4 and having aii air pipe 5 leading tlierefrom into the storage tank l.

, lii.the prcfei'red embodiincnt of the iiivention. tlie pistoii (i is iiioiuited directly on the engine shaft 7 and has oiie eiid of the liiib thereof provided with a cliitcli face 8 adapted to be engaged by -the taii'rcslnmdiiig face of a shit' table. chitch 9 which is spliiied to tlie` engine slnil't 'i' aiid daptcd to bo iiioved iiito und out ofciigngciucntwith the cliitcli face s of the.

The cvliiu er 3 is made iii separable sectioii.` aa iiidicated iii Fig. 4 where it is shown to be divided oii a central line 13 to enable the pistoii to be placed tlierciii und renioi'ed therefroin. 'l`he `-ieetioii8 of the cylinder are provided with base flanges 14 adapted to be iolted to one or more supporting briicltets 15 secured to the frame 10 of the motor vehicle as indicuted iii Fig. 4. 'I`he cylinder eections are also provided with liigs l'i'- adapting them to be seciirely fustened together by means of bolts 18 pas-'big through said liigs irs shown iii Fig. 3.

The body of the cylinder is provided 00 ,at intervala` with pliinger pocketsz prefernbly arranguljn pairs sit e by sideas iiidicated iii Fig. 4, iii which are arranged a correspondiii number of cylindrical phingera 2.1,two'o such pluiigeni i carried by each one of a series of piaton wings or bladcs 20 each subetantially iii the form of ii half disk us shown in Fig. 6..
